 |
|
I now have a total of 4 x 1GB sticks on my Asus P5B Deluxe/WiFi-AP. I can't understand why my system only has 3GB memory available. Below is a relevant part of dmidecode output, followed by memory usage and emerge info. Any insight would be appreciated.

his emerge --info show's the kernel version, and it's x86-64
i have no clue how you can't see your fourth GiB. maybe world compiled for 32bit...
what's the output of
| Code: |
#include <stdio.h>
#include <stdlib.h>
int main()
{
printf( "%d %d", sizeof(size_t), sizeof(void*) );
return 0;
}
|
when compiled with your portage CFLAGS?

I would certainly hope that uname -a shows x86_64, since his emerge --info definitely does. |

try enabling in your bios memory remap
but this might cause trouble to some onboard devices, google for P5B memory remaping |

Thank you krinn. Googled your search string as per your recommendation. Top match tells me that memory remap is activated from BIOS/Advanced/Chipset/Northbridge Chipset Configuration.
Upon reboot, I now have a satisfying 4G available memory. So far, no apparent problem with onboard devices.

Is it not possible to change to x86_64 after the kernel is compiled?
